Onychomatricoma is a rare tumour that derives from the nail matrix and grows within the nail plate. The clinical presentation can mimic many other tumours and conditions, and surgical biopsy and histopathological examination are necessary to confirm the diagnosis. As nail surgery is a painful experience for the patient and sometimes can leave permanent onychodistrophy, more precise preoperative diagnosis is needed to distinguish onychomatricoma from other nail diseases more accurately and to limit surgical interventions. The objective of this study was to evaluate current literature on imaging techniques for the diagnosis of onychomatricoma in order to understand how this technology can help the presurgical diagnosis of this tumour. We searched in the Cochrane Skin Group Specialised library, Medline, Embase and LILACS databases all studies evaluating imaging technique for the diagnosis of onychomatricoma up to February 2018. We found that not only nail dermoscopy, but also reflectance confocal microscopy, optical coherence tomography, ultrasonography and magnetic resonance can be useful in this field.

“…Other possible features include hairpin vessels (vascular loops that can twist or bend), splinter hemorrhages, the rainbow sign (circumscribed polychromatic area), and a pink background. There is thickening and convex deformity of the free margin, with the presence of distinct honeycomb-like cavities, considered pathognomonic (Cinotti et al 2018;Marchetti et al 2018;Okon et al 2017;Lesort et al 2015) (Fig. 70).…”

Onychoscopy is becoming more and more frequently utilized for the diagnosis of nail disorders. It allows visualization of varying details of nails that can be diagnostic of several diseases, in particular periungual and subungual warts and onychomycosis. The onychoscopy criteria for majority of the inflammatory and infective nail disorders are evolving at a rapid pace. Distinctive dermoscopic signs that are exclusive to distal subungual onychomycosis and to traumatic onycholysis have also been described and allow a differential diagnosis from psoriasis. It has now become very essential for all the clinicians to learn the technique of
